Exploiting Visibility Correlation in Direct Illumination
The visibility function in direct illumination describes the binary visibility over a light source, e.g., an environment map. Intuitively, the visibility is often strongly correla...

Quality Assessment of Degraded Iris Images Acquired in the Visible Wavelength
—Data quality assessment is a key issue, in order to broad the applicability of iris biometrics to unconstrained imaging conditions. Previous research efforts sought to use visib...

Spatio-temporal upsampling on the GPU
Pixel processing is becoming increasingly expensive for real-time applications due to the complexity of today’s shaders and highresolution framebuffers. However, most shading re...

Fast Soft Self-Shadowing on Dynamic Height Fields
We present a new, real-time method for rendering soft shadows from large light sources or lighting environments on dynamic height fields. The method first computes a horizon map f...
